Low carbon building design is an important aspect to achieve sustainable development in our community. Throughout the years, ArchSD has been striving to bring in low carbon design elements into architectural projects. We believe that the emergence of applying low carbon design initiatives can provide a significant effect on the need for creating more sustainable and energy efficient buildings and facilities, which will benefit our society at the end.
Energy conservation is one of our prime concerns when we consider adopting low carbon design in our projects.Since 2011 some ArchSD projects have been selected as energy efficiency demonstration projects for testing out the extent of saving when all the energy saving equioment/systems were put together.
In these demonstration projects, energy efficient designs and technologies such as use of energy efficient building materials, installation of building energy management system, adoption of automatic building ventilation system, adoption of renewable energy, installation of efficient lighting control, optimization of equipment control etc. have been widely adopted. It is anticipated that these projects will set good examples in promoting the use of energy efficient designs and technologies for the construction industry.
This project, a holistic approach has been adopted to enhance the environmental performance including various aspects.
Design and Features:
In addition to adopting common environmental and energy efficient features that are included in other government projects (e.g. heat energy reclaim for ventilation system; T5 energy efficient fluorescent tubes with electronic ballast; occupancy sensors and daylight sensors and light emitting diode (LED) type exit signs etc.), this project has incorporated addtional environmental and energy efficient features, with the purpose of exploring and identifying suitable technologies for wider adoption in future.
Examples of these additional environmental and energy efficient features are highlighted below:
It is expected that the annual Greenhouse Gas (GHG) saving for the school would be about 30 tonnes carbon dioxide equivalent (CO2-e), about 40% less emission comparing with that of a typical school in Hong Kong.
The project has obtained a certificate in Hong Kong Building Environmental Assessment Method (BEAM 4/04) with platinum rating in 2012.
The scope of the project comprises the development of new cruise terminal facilities on a site of 7.6 hectares at the southern end of the former runway at the Kai Tak Airport.
The cruise terminal has four main atria placed at regular intervals extending to the full height of a 3-storey building. The atria design allows natural light into the premises in order to provide a natural and vibrant environment.
A green landscape design at the roof deck has been adopted to provide a breathtaking waterfront views for the public to enjoy even if they are not taking a cruise vacation. The design also serves as an urban oasis for both tourists and the public to enjoy the tranquil surroundings and undertake leisure activities.
Sustainable design features such as photovoltaic systems, rain water recycling system for irrigation, service-on-demand controls for escalators and passenger conveyors, carbon dioxide sensors and building energy management system are widely used within the terminal building. The building will be connected to District Cooling System which provides chilled water to the air-conditioning system to achieve energy efficient air-conditioning.
This building is a 22-storey government building, offering a total net operational floor area of about 33,000 m2 to house various government departments, in particular Trade and Industry Department. In addition, a community hall with a seating capacity of 450 persons and other supporting facilities will be provided for organizing community activities in the Kowloon City district.
Design and Features:
The construction of the building aims for certification under the BEAM 4/04 with platinum rating and the Leadership in Energy and Environmental Design (LEED) certification programme, which will incorporate many energy-efficient designs and technologies. Various applications of renewable energy technologies, photovoltaic systems, solar hot water systems, solar chimney and daylight sun-tubes will be adopted. The building will also be connected to the District Cooling System to achieve energy efficient air-conditioning and to provide more space for green roof.
Other energy conservation and environmental features will also be applied in the building, which include:
Apart from planting lush landscaping on the ground floor, landscaped elevated walkway and the main roof, the building tower will feature vertical greening on the building façades. It is anticipated that the overall greening of this project will account for more than 30% of the site area.
In terms of recycling and other environmental features, the project will also collect and recycle rainwater for landscape irrigation, adopt an automatic refuse collection system and reuse inert construction waste to minimize disposal of waste to the public fill reception facilities.
The project is scheduled for completion in 2014.
